  • Holding Or Fastening Of Disk On Rotational Shaft (AREA)

Abstract

PURPOSE:To reduce the operating force at the time of loading and also, enable transmitting the rotation of a spindle shaft 6 without slipping by providing a fine rib connecting between annular ribs and holding and rotating the central part by engaging with a disk engaging member at a disk driving device side. CONSTITUTION:A center core 2 with an opening larger than the diameter of a spindle shaft 6 is provided and a metallic absorbing yoke 1 having a V letter end face which is abutted to the spindle shaft 6 is also provided. The abrasion is reduced due to inserting and extracting, in addition, the centering is performed by utilizing a sliding load forces of a head and a magnetic disk at the time of disk rotation. Furthermore, the fine rib is provided to fit to a groove of a spindle hub 7. By this method, the operating force of loading is reduced and rotating torque of the spindle 6 is transmitted to a magnetic disk 4 without slipping.
